Hands-On Help

  • Triage

    Fix broken checkout, payment failures, missing orders, webhook retries, or PHP errors that block revenue.

  • Integration

    Payment gateways, webhooks, receipts, refunds, and idempotency, built to survive real traffic.

  • Stabilize

    Performance tuning, MySQL bottlenecks, caching, and cleanup that makes the system predictable.

Who I work with

  • eCommerce sites with custom PHP code
  • Founders preparing to launch or scale
  • Agencies needing a reliable PHP developer
  • Teams stuck with AI-generated or rushed PHP code

Not a fit

  • Projects without code or deployment access
  • Pure training or coaching engagements
  • Adult, gambling, or other high risk niches
When our legacy cart system became obsolete, Vincy rebuilt a custom cart that fit our modern front-end perfectly. She quickly understood complex requirements, improved performance, and delivered exactly what we needed. The solution worked flawlessly from day one and scaled with our workflow. Reliable, hands-on, and highly recommended for serious eCommerce projects.

FAQ

Short answers to common questions before we start.

  • Do you work on existing messy PHP codebases?

    Yes. I regularly step into legacy or custom PHP systems and stabilize them without a full rewrite.

  • Can you do small work and urgent bugfixes?

    Often yes, depending on scope and access. Use the form below and mention “urgent” in your message.

  • How do you handle estimates and billing?

    I provide a scoped estimate after review. Billing is milestone-based for projects or monthly for retainers.

  • Can I have a video call or chat with you?

    Yes. Just reach out and we'll take it from there.

  • Which gateways do you support?

    Stripe, PayPal, Authorize.net, 2Checkout, SagePay, Quantum, CCAvenue, Razorpay and others. Share the gateway name and I will confirm the best path.

  • Do you offer ongoing support after launch?

    Yes. I offer a maintenance retainer for ongoing improvements and stability.

  • What access do you need to start?

    Typically repo or code snapshot, staging access or repro steps, and relevant logs.

  • Can you work with agencies under NDA?

    Yes. I am comfortable working under NDA with agencies or internal teams.
